Isomalt Gems - How To Fill Mold Safely?

I have a question and I hope you don't laugh me out of the forum. I'm typing this with bandaids all over one finger. I attempted my first Isomalt gems and burned my finger badly. I have the First Impressions silicone mold with the 1/2" gems. What can I use to fill the mold with the tiny amount of isomalt required safely?

While it's not perfect, it worked pretty well. Popped it into the microwave for a few seconds when the sugar thickened too much, and was able to handle it w/o gloves. I was able to pour even tiny jewels, like the little ones on the crown. I did them first when the sugar was very liquidy.

I just got into making my own gems and realized the same difficulty. Melting the isomoalt, then getting it poured then re-melting, pouring, on and on... I knew there had to be a better way. I turned to my metal measuring spoons, right over a candle. AWESOME and ingenious. I can melt small amounts at a time and pour into the molds perfectly. No muss, no fuss and clear.

My only challenge right now is the humidity. I thought I could make them ahead of time and store. But I was wrong. First they got sticky, then they they went from cloudy to white. even the blue are aweful. They're all ruined.
